In the context of the rapid development of new productive forces, the industry-education integration model in vocational education faces adaptive issues such as a mismatch of talent supply and demand, lack of coordination mechanisms, and lagging service systems. Based on the perspective of lifelong learning, this study analyzes the connotation of industry-education integration in a broad sense and constructs a three-dimensional optimization path of “time-space-technology.” In the time dimension, it connects academic education with continuing education. In the spatial dimension, it integrates formal and informal learning environments. In the technical dimension, it promotes the collaborative development of digital technology and digitization, forming an industry-education integration ecosystem that covers the entire career cycle.
